Abstract: A device for securing a length of rope includes a housing with at least one pair of apertures therein defining a passage through the housing for receiving a line of rope. The device includes a pin extending at least partially through the interior of the housing, and a torsion spring disposed within the housing. The device further includes at least one cam member with a grooved edge portion, pivotally mounted on the pin and biased by the torsion spring so as to pivot the cam member's grooved edge portion in a direction towards an interior wall of the housing for engaging a line of rope received within the passage between the cam member's grooved edge portion and the interior wall. The at least one cam member has a lever depending from the cam member, which enables pivotal movement of the cam.
